Questions

Is there a KiCad symbol and footprint for the AT24CS64-MAHM-T?

Yes. The symbol is Memory_EEPROM:AT24CS64-MAHM and the footprint Package_DFN_QFN:DFN-8-1EP_3x2mm_P0.5mm_EP1.3x1.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AT24CS64-MAHM-T?

UDFN-8-EP(2x3), with 9 pins. Its footprint is drawn on this page.

Where is the AT24CS64-MAHM-T datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the AT24CS64-MAHM-T?

JLCPCB lists it as part C2061553, with 388 in stock; the sellers' links on this page open their listings.

What can replace the AT24CS64-MAHM-T?

Parts like it in the library: the AT24CS02-MAHM-T by Microchip Technology, the AT24CS01-MAHM-T by Microchip Technology, the AT24CS32-MAHM-T by Microchip Technology and the AT24CS16-MAHM-E by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
